(57) Abstract:
A system for extracting a bodily fluid sample (e.g., an interstitial fluid [ISF] sample) and monitoring an analyte therein
includes a disposable cartridge and a local controller module. The disposable cartridge includes a sampling module
adapted to extract a bodily fluid sample and an analysis module adapted to measure an analyte (e.g., glucose) in the
bodily fluid sample. The local controller module is in electronic communication with the disposable cartridge and is
adapted to receive and store measurement data from the analysis module. An ISF extraction device includes a
penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently,
extracting an ISF sample therefrom. The device also includes a pressure ring(s) adapted for applying pressure to the
user's skin layer in the vicinity of the target site. The device is configured such that the pressure ring(s) is capable of
applying pressure in an oscillating manner whereby an ISF glucose lag of the ISF sample extracted by the penetration
member is mitigated. A method for extracting ISF includes providing an ISF fluid extraction device with a penetration
member and a pressure ring(s). Next, a user's skin layer is contacted by the pressure ring(s) and penetrated by the
penetration member. An ISF sample is then extracted from the user's skin layer while pressure is being applied in an
oscillating manner by the pressure ring(s). The oscillating pressure mitigates an ISF glucose lag of the extracted ISF
sample extracted.
